Chen Fei looked at the formation in front of him and extended his Qianyuan Sword to tap lightly on the membrane of light, causing faint ripples to spread across it.
Attempting a direct breach would undoubtedly trigger changes in the formation. This would lead to increased commotion, likely attracting other practitioners at the Aperture Tempering realm. Such a scenario would result in numerous uncertainties, and it remained questionable whether he could secure the treasure amidst the ensuing chaos. Chen Fei's current combat strength could handle two or three Aperture Tempering realm initial-stage opponents, but facing more would become increasingly challenging.
With a furrowed brow, Chen Fei pointed his finger forward, and a black sword thread appeared before the light membrane. The membrane started to ripple in concentric circles, evolving into waves. The brightness of the light membrane began to fluctuate, and the elemental energy within it quivered.
